Standard rules of the online world are the same as dealing with the faewylds, and online dating is no exception:

Never utter your true name. Ensure someone knows where and who you are before engaging in anyone from there. Check in with them until no longer feasible to. Take nothing for free, assume poisons could be attached. Assume all words spoken are lies. If it seems too good or convenient to be true, it probably is. All that is taken will one day be returned, with interest.

This fellow broke every rule.
